The method includes: providing a prediction engine associated with the storage system including at least one storage device, the prediction engine being initiated at an installation time of the at least one storage device; automatically determining lifespan values of the at least one storage device to assign the global lifespan of the storage system, the global lifespan being dependent on the installation time of the at least one storage device; replacing, responsive to a time-based failure event, a storage device of the at least one storage device; and subsequently monitoring, using the prediction engine, the global lifespan of the storage system based on the time-based failure event to define, at least in part, an optimized lifespan of the storage system.

BACKGROUND

The present invention relates in general to data storage technology, and more particularly, to a method for improving life estimation mechanism of a storage system of a computing system based on statistical modeling of failure data of storage device(s).

As understood, a storage system typically includes one or more storage devices that store data as segregated blocks of storage on various storage media, such as, magnetic, optical data storage disks or server hard disk devices. For instance, in magnetic disk storage systems, a storage device, such as, hard disk drive (HDD), includes one or more hard disks and an HDD controller to manage local operations concerning the disks. Advances in data storage landscapes have also led to solid-state storage devices (SSDs), such as, flash memory devices, and server hard disk devices. Disadvantageously, these storage devices are often affected by environmental factors, such as, humidity, temperature, dust, debris and handling, that are specific at which the storage devices reside which, in one example, could impact lifespan of such storage devices. Predicting impeding failure of storage media helps protect against catastrophic data loss, for example, by suggesting a back-up of data and/or replace of the storage media.

Accordingly, there is a continuing need in the art for better storage life estimation to account for failure and durability of such storage devices.

DETAILED DESCRIPTION

The present disclosure is directed to, inter alia, embodiments of a method and a system for predicting an optimized global lifespan of a storage system, for instance, having one or more storage devices, of a computing system. By way of example, the present invention relates to, for instance, to improving a global lifespan of the storage system by predicting future failure events of the storage device(s) based on statistical modeling of the past failure events of storage device(s). As understood, storage system typically includes one or more storage devices that are utilized for storing data on various storage disks or storage media, such as, magnetic, optical data storage disks or server hard disk devices. As one skilled in the art will understand, each of the storage devices of the storage system may, for instance, have a global lifespan that is based on benchmark values and technical specification provided by the vendor (for instance, providing the storage system). Disadvantageously, such global lifespan may not be optimal, for instance, owing to environmental factors related to the locations at which the storage devices reside, and/or issues, such as, handling of the storage devices. In one embodiment of the present invention, an optimized lifespan of the storage system is customized to an environment of a customer's site in which the storage system is located, without being affected by the environmental variables, such as, humidity, temperature, dust, and the like, related to that specific customer site. Advantageously, such optimized lifespan of the storage system reduces the costs related to shipping and undesirable replacing of a functioning storage device.

Referring to FIG. 1A, in one embodiment, is a system 100 for improving a global lifespan of a storage system 112/118 of a computing system 102, in accordance with one or more aspects of the present invention. As depicted in FIG. 1A, computing system 102 is only illustrative of various types of computer infrastructures for implementing the invention. For example, in one embodiment, computing system is only representative of various possible computer systems that can include numerous combinations of hardware. As one skilled in the art will understand, computing system 102 can include any specific purpose computing article of manufacture including hardware and/or computer program code for performing specific functions, any computing article of manufacture that includes a combination of specific purpose and general purpose hardware/software, and the like. In each case, the program code and hardware can be created using standard programming and engineering techniques, respectively.

By way of example, and as depicted in FIG. 1A, computing system 102 may include a data processing system 104 which, in one embodiment, is suitable for storing and/or executing program code, such as, program code for performing processes described herein, and includes one or more processor(s) 106 coupled directly or indirectly to a memory 108 through, one or more buses or other connections 110. As understood, in operation, processor 106 obtains from memory 108 one or more instructions for execution by the processor. Memory 108 may include local memory (not shown) employed during actual execution of the program code, storage system, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from storage system during program code execution. By way of example, the storage system 112 of data processing system 104 may include, for instance, removable/non-removable, volatile/non-volatile storage system having one or more storage devices. A non-limiting list of examples of memory 108 includes a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. Note that, in one embodiment, the method and the system disclosed herein may be implemented to improve lifespans of each of the storage devices of the storage system 112 of the memory 108.

Additionally, memory 108 includes a program 114 having a set (at least one) of program modules 116, by way of example, and not limitation, as well as operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. By way of example, program modules 116 may typically carry out the functions and/or methodologies of embodiments of the invention described herein. In one example, processor 106 executes program 114, such as, prediction engine which is stored in memory 108 with a set of modules 116. As further described below in detail, the prediction engine (not shown) may also be stored at a computer node, such as a server 122 that is in communication with the computing system 102. In one embodiment, the prediction engine (not shown) is a program that is configured with a pre-defined algorithm which, for instance, facilitates improving a lifespan of the storage system disclosed herein, by predicting future failure events of the storage device(s) based on the statistical modeling of the past failure events, thereby defining an optimized lifespan of (for instance, each of the storage device(s)) of the storage system 112. As understood, the processor 106 can read and/or write data from the prediction engine (not shown) of the memory 108.

Further, data processing system 104 may also be coupled with storage system 118 that, for instance, provide sufficient storage for storing programs and data, and may include one or more storage devices, such as, an internal storage device or an attached or network accessible storage. In one example, storage system 118 may include one or more storage devices, such as, for instance, a magnetic disk drive or an optical disk drive. In another example, the storage system 118 may also include storage media, such as, floppy drives, ZIP drives, and other disk drives and the like. As understood, computer programs in storage system 118 may be loaded into memory 108 and executed by the processor 106. Note that, in one embodiment, the method and the system disclosed herein may also be implemented to improve lifespans of (for instance, each of the storage device(s)) of the storage system 118.

Additionally, data processing system 104 may be coupled with one or more external devices 120 either directly or through device interfaces 114, such as, graphical user interfaces 122 b (see FIG. 1B). By way of example, the external devices 120 include, but are not limited to, keyboards, pointing devices, displays, and the like. Additionally, although not depicted, network adapters (not shown) may also be coupled to the system to enable the data processing system to become coupled to other data processing systems through intervening private or public networks. Modems, cable modem, and Ethernet cards are just a few of the currently available types of network adapters (not shown).

In one embodiment, and as described above, the computing system 102 associated with a user is in communication with a remote server 122 (FIG. 1A) via wired or wireless network 124 (FIG. 1A). Note that, in one embodiment, FIG. 1B depicts various components of the system that are either located on the computing system 102, or connected directly or indirectly with the computing system 102, and, for instance, can be preferentially used to implement functions and/or methodologies of embodiments of the invention. By way of example, the server 122 can, in one embodiment, run a Dynamic Host Configuration Protocol (DHCP) server component which, in one example, can dynamically assign IP addresses to a dedicated server that would be hosting the prediction engine (not shown) so as to enable storage administrators to easily access the desired information over the web. In such an example, the prediction engine (not shown) may be hosted on a user-specific network component 122 a of server 122. As one skilled in the art will understand, DHCP server is a protocol used to communicate between servers and compute node during the initial boot of the compute node. DHCP server defines the protocol by which the server 122 supplies networking and startup information to the node, such as its IP address and getaway, and provides an initial bringup kernel to the node. Note that, as described above, in another embodiment, the prediction engine may also be stored in memory 108 of the data processing system 104 with a set of modules 116.

According to an embodiment, the prediction engine (not shown) may be performed in a statistical programming environment, such as, “Statistical Package for the Social Sciences” (SPSS®) component 122 e of the server 122. As understood, SPSS® is web-based software for performing data mining and statistical analysis which, for instance, may be configured to work with other components, as well as perform predictive analysis using the pre-defined algorithm of the prediction engine (not shown). As described above, the prediction engine is software that has been configured with a pre-defined algorithm to calculate a lifespan of the storage system disclosed herein.

The prediction engine (not shown), in accordance with the present invention, is configured to be initiated when a user installs one or more storage device(s) of the storage system 112/118. By way of example, an installation time of the storage device(s) of the storage system 112/118, for instance, defines an installation time of the prediction engine (not shown) in predictive maintenance and reporting solution (SPSS®) component 122 d (see FIG. 1B) of server 122. Further, upon initiation, the prediction engine (not shown) will assume a global lifespan of the storage system 112/118, for instance, by ascertaining a lifespan value of each storage device of the storage system 112/118, based on the benchmark values and technical specifications provided by a vendor, the time and/or day of installation of each of the storage devices and the number of the storage device(s) installed, respectively. Further, the global lifespan of the storage system 112/118, for instance, may be calculated by aggregating the lifespan values of each of the storage device(s) of the storage system 112/118, and simply averaging the aggregated lifespan values of the installed storage device(s). As used herein, “lifespan value” refers to a length of time, for which a storage device is assumed to function, depending on the day and/or time of installation of the storage device, as a baseline. Further, the SPSS® component 122 d of the server 122, assigns the aggregated and averaged lifespan values of the installed storage device(s) to the prediction engine (not shown) as a global lifespan value of the storage system 112/118, which, in one example, as a baseline for future reference.

By way of example, and in one embodiment, a storage device of the storage system 112/118 is replaced, for instance, when a storage device of the storage system 112/118 malfunctions or is identified as not operating correctly, i.e., a failure event of the storage device occurs. As used herein, “time-based failure event” refers to a failure event of the storage device that is measured starting from the day/time of installation of the storage device to a time the storage device fails. Upon replacing the failed storage device of the storage system 112/118, the SPSS® component 122 d of the server 122 is configured, in accordance with the present invention, to modify the global lifespan value of the storage system 112/118 so as to provide a custom-global lifespan value (F_(a)) of the storage system 112/118 having the replaced storage device. For example, the custom-global lifespan value (F_(a)) of the storage system 112/118 having the replaced storage device is calculated using the pre-defined algorithm of the prediction engine (not shown):

$F_{a} = {G_{a} \pm \left\lbrack {F_{d}\left( \frac{X_{n}}{X_{t}} \right)} \right\rbrack}$ where G_(a) is the global lifespan value of the storage system 112/118, F_(d) is days between the installation time and the failure event of the storage device, X_(n) is a number of the storage device(s) during the failure event, and X_(t) is the total amount of the storage device(s) of the storage system 112/116, and the “±” being dependent on the days between the installation time and the failure event, and the global lifespan value of the storage system.

By way of example, and in one embodiment, if the days between the installation time and the failure event (F_(d)) of the storage device were to exceed the global lifespan value, (i.e., if the storage device were to function beyond its global lifespan value), before a failure event occurs, then the custom-global lifespan value (F_(a)) of the storage system 112/118 having the replaced storage device may be calculated using the pre-defined algorithm

$F_{a} = {G_{a} + {\left\lbrack {F_{d}\left( \frac{X_{n}}{X_{t}} \right)} \right\rbrack.}}$

In another example, if the storage device were to fail prior to its global lifespan value, i.e., if the days between the installation time and the failure event (F_(d)) of the storage device were to be less than its global lifespan value, then the custom-global lifespan value (F_(a)) of the storage system 112/118 having the replaced storage device may be calculated using the pre-defined algorithm

$F_{a} = {G_{a} - \left\lbrack {F_{d}\left( \frac{X_{n}}{X_{t}} \right)} \right\rbrack}$

In another embodiment, when a replaced storage device of the storage system 112/118 malfunctions or fails, in an additional time-based failure event, the failed storage device may be replaced with yet another storage device. In such an example, the SPSS® component 122 d of the server 122 is configured to modify the global lifespan value of the storage system 112/118 so as to provide an additional custom-global lifespan value (F_(a1)) of the storage system having the additional replaced storage device. In such a case, the additional custom-global lifespan value (F_(a1)) of the storage system having the additional replaced storage device is calculated using the pre-defined algorithm

$F_{a\; 1} = {F_{a} \pm \left\lbrack {F_{d}\left( \frac{X_{n}}{X_{t}} \right)} \right\rbrack}$ where Fa is the custom-global lifespan value (F_(a)) of the storage system 112/118 having the replaced storage device, F_(d) is days between the installation time and the failure event of the storage device, X_(n) is a number of the storage device(s) during the failure event, and X_(t) is the total amount of the storage device(s) of the storage system 112/116.

By way of example, and in one embodiment, if the days between the installation time and the failure event (F_(d)) of the storage device were to exceed the custom-global lifespan value (F_(a)), i.e., if the storage device were to function beyond its custom-global lifespan value (F_(a)), before a failure event occurs, then the additional custom-global lifespan value (F_(a1)) of the storage system 112/118 having the replaced storage device may be calculated using the pre-defined algorithm

$F_{a\; 1} = {F_{a} + \left\lbrack {F_{d}\left( \frac{X_{n}}{X_{t}} \right)} \right\rbrack}$

In another example, if the storage device were to fail prior to its custom-global lifespan value (F_(a)), i.e., if the days between the installation time and the failure event (F_(d)) of the storage device were to be less than its global lifespan value, then the additional custom-global lifespan value (F_(a1)) of the storage system 112/118 having the replaced storage device may be calculated using the pre-defined algorithm

$F_{a\; 1} = {F_{a} - {\left\lbrack {F_{d}\left( \frac{X_{n}}{X_{t}} \right)} \right\rbrack.}}$

Additionally, in an enhanced embodiment, each of the global lifespan value, the custom-global lifespan value (F_(a)) and the additional custom-global lifespan value (F_(a1)) extracted from the SPSS® component 122 d of the server 122, may be stored discretely, for instance, at a lifespan database, in the database component 122 c of the server 122. As understood, this lifespan database stored at database component 122 c may, in one example, function as a repository for all the information extracted from the SPSS® component 122 e of the server 122 and the storage system 112/118, respectively. Further, in one embodiment, the lifespan database may be configured to be updated continuously, for instance, by dynamically monitoring each of storage device, the replaced storage device and the additional replaced storage device of the storage system 112/118. Note that, in one embodiment, each of these storage devices are monitored discretely so as to update the lifespan database discretely by, for instance, integrating the data processing system 104 (see FIG. 1A) with an IT product architecture, such as, for instance, IBM Tivoli Netcool/Impact™ (NCI). As understood, Netcool 122 d is a set of runable server components that work together to provide event management and integration functionality for business service management. For instance, each of these storage device(s) (for instance, including the replaced storage device and the additional replaced storage device) are monitored from their corresponding installation day/time to their failure events, respectively, and their information is discretely updated. This, in turn, can facilitate predicting any impeding/future failure event of the storage device(s), based on the statistical modeling of the past failure events of the storage device(s). As one skilled in the art will understand, the discrete dynamically monitoring of each of the storage device, the replaced storage device and the additional replaced storage device, and replacing the failed storage device(s) provide serialized and parallelized processing steps to predict any future failure events, thereby defining an optimized global lifespan of the storage system 112/118. Note that, in one embodiment, the user can communicate with an administrator and/or technician remotely to provide the information regarding the optimized lifespan of the storage system 112/118, using, for instance, a simple network management protocol (SNMP). As one skilled in the art will understand, simple network management protocol (SNMP) is a common protocol used for managing network infrastructure over the network 124. Alternatively, the administrator and/or technician may access the information remotely from the lifespan database located in the database component 122 c of the server 122, using, for instance, the SNMP protocol.

According to one embodiment, an impeding/future failure event of the remaining storage devices of the storage system 112/118, for instance, subsequent to the replaced storage device(s), may be predicted based on the statistical modeling of the failure event of the initially installed storage device. This, for instance, may be accomplished by extracting the custom-global lifespan value (F_(a)) (which, for instance, is an accumulative value) stored in the lifespan database at the database component 122 c of the server 122, and subtracting the custom-global lifespan value (F_(a)) from the global lifespan value (G_(a)), thereby predicting an impeding failure of the remaining initially installed storage devices. Advantageously, this, for instance, results in each past failure event predicting an impeding failure event by, for instance, recalculating the global lifespan values of the storage system, not based on the actual benchmark or technical specifications provided by the vendor, but instead be calculated as an average for the environment on which it is deployed. Similarly, an impeding failure of the remaining replaced storage device of the storage system 112/118, in the case of an additional replaced storage device(s) may be predicted, by substituting the value of custom-global lifespan value (F_(a)) for global lifespan value (G_(a)), i.e., subtracting the additional custom-global lifespan value (F_(a1)) from the custom-global lifespan value (F_(a)).

In an enhanced embodiment, computing system 102 associated with the user may be coupled with one or more interfaces, such as, a graphical user interface (GUI) component 122 b, which, for instance, facilitates human/computer interactions, for visualizing reports, (for example, such as, day/time of installation of the storage system, media manufacturer, system device, information regarding the lifespan values, etc.), alerts (e.g., failure events, impeding failure events, etc.), as well as allowing to access the lifespan database for any required information. Additionally, the GUI 122 b also allows communication with other computers or storage area networks (SAN) and the like.

FIG. 3 is an overview of process 300 for providing an optimized global lifespan of a storage system by predicting future failure events of the storage device(s) thereof, based on statistical modeling of the past failure events of the storage devices, in accordance with an aspect of the present invention. The process 300 begins with providing 302 a prediction engine associated with a storage system that is initiated at an installation time of at least one storage device of the storage system, and lifespan values of the at least one storage device may be automatically determined 304 to assign a global lifespan that is dependent on the installation time of the storage system. Further, the process 300 proceeds to replace 306 a storage device of the at least one storage device, in response to a time-based failure event, and the global lifespan of the storage system is modified 308, using the prediction engine, and based on the time-based failure event, to define, at least in part, an optimized lifespan of the storage system.
